I was in there deep, as I was in most. There always CAN be a signal to have them let up so you can get air, but I don't think I ever used it, especially with her as she wasn't a BBW type and I could maneuver her. I wish I could take her on again.
One that I REALLY loved taking on was this one who WAS more of a BBW. I had long talked to her and by the time we got together I was so hyped. She has a 50" ass and it's perfectly round. Had posted about her many times here. We were a natural and from minute one, I told her to go all out on my face. For her, we decided I was going to fight it out...my face vs her ass. We did many different scenes and positions and it was epic. My face has never been so far inside any ladies ass and she enjoyed and trashtalked me (which I couldn't hear because I was in so deep, until we watched it back). Her ass and my face belonged together, but yeah, I had to squirm and roll. Worth it 100%
